Security Features

For users concerned with security, it would be very helpful if you offered a page with a description of your security on your website. for example, it would be useful to know:

- the encryption used in device to server and server to device communication.
- whether data stored on servers is encrypted, and if so, using which cipher.
- whether passwords are salted and hashed.

SMS can contain data requiring some level of security, for example, one time codes for login/banking, and many users will want some assurance that messages are held and transmitted over the web securely.

On my Web interface i believe i just received 2 sms messages from a person i don't know... these messages did not even appear on my phone. This may be a huge security flaw. i have contacted support and included a screenshot.
